Accounts payable receivable software compared: one suite vs separate AP and AR tools, ledger sync, cash flow view and the best options for contractors.

Every contractor runs two money streams at the same time. Bills come in from subs, suppliers and equipment rental yards, and invoices go out to owners, GCs and homeowners. Accounts payable receivable software is how you keep both streams moving without living in a spreadsheet, and the real question is not which app has the longest feature list. It is whether you run payables and receivables in one suite or in two best-of-breed tools, and how cleanly either setup talks to your general ledger.
I ran three restoration companies for over 14 years. Bills show up whether you chase them or not. Receivables only show up if somebody chases them. That gap is where most contractors run short on cash, and it is why this guide treats AP and AR as one cash picture, not two separate departments. If you need the basic definitions first, start with our explainer on accounts payable vs. accounts receivable.
KEY TAKEAWAYS
Payables and receivables are mirror images. AP captures a bill, codes it to a job, routes it for approval, pays it and records the payment. AR creates an invoice, sends it, follows up until it is paid and records the deposit. Software automates the steps in between so nobody retypes numbers.
| Step | Accounts payable (money out) | Accounts receivable (money in) |
|---|---|---|
| Capture | Read bills from email or uploads and pull vendor, amount, due date | Create invoices from estimates, progress billing or the accounting system |
| Code | Assign job, cost code and GL account | Tie the invoice to the job, customer and contract |
| Approve or send | Route to the PM or owner for approval | Deliver by email, text or portal with a payment link |
| Pay or collect | Pay by ACH, check, card or wire on schedule | Follow up on a schedule until paid, then take the payment |
| Record | Mark the bill paid and sync the payment to the ledger | Apply the payment to the invoice and sync to the ledger |
| Report | AP aging, cash requirements, 1099 data | AR aging, promised payments, DSO |
This is the first real decision. A suite handles AP and AR in one product, with one login, one vendor and customer list, and one sync to your accounting system. Best-of-breed means you pick the strongest tool for each side and connect both to the same ledger.
| Factor | One AP/AR suite | Separate best-of-breed tools |
|---|---|---|
| Setup | One connection to the ledger, one set of users | Two connections, two sets of settings |
| Depth | Good enough on both sides, rarely the best at either | Deeper on the side that hurts most |
| Cost | One subscription, often per user | Two subscriptions; can still cost less if you only need depth on one side |
| Data | Shared customer and vendor records | Each tool reads from the ledger, so the ledger must be clean |
| Risk | If the suite is weak on collections, AR stays manual | More moving parts; someone has to own each sync |
| Best for | Small offices with one bookkeeper doing both | Firms where one side, usually collections, is the bottleneck |
Here is my honest take from the contractor side. Payables are mostly a control problem: make sure the right bill gets paid once, after the right paperwork is in. Receivables are mostly a follow-up problem: make sure every open invoice gets a polite, persistent nudge until the money lands. Suites tend to be built around the control problem. If your real pain is that invoices sit at 45 days because nobody had time to call, a suite's reminder feature may not be enough, and a dedicated receivables layer is worth a look. Our roundup of the best accounts receivable software covers that side in depth.
Whatever you choose, the general ledger in QuickBooks, Xero, Sage or your ERP has to stay the source of truth. The AP and AR tools are workbenches. The ledger is the record. Before you sign up for anything, get answers to four questions.
| 1 | Which direction does it sync? One-way sync pushes data into the ledger but does not pull changes back. Two-way sync keeps both sides matched when someone edits a bill or invoice in either place. Ask: if your bookkeeper voids an invoice in QuickBooks, does the AR tool stop chasing it? |
| 2 | What exactly syncs? Vendors, customers, bills, invoices, payments, credits, classes, jobs and attachments are all separate items. Some tools sync invoices but not edits, or payments but not the job or class. Get the list in writing. |
| 3 | Which plan tier includes it? Automatic two-way sync is often reserved for a higher plan. BILL, for example, lists manual CSV import and export on its entry plan and automatic two-way sync with QuickBooks Online and Xero on higher tiers (per the BILL pricing page in November 2026). |
| 4 | Where do payments land? If customers pay through a third-party link, the deposit may hit your bank as one lump net of fees. Your ledger needs a clearing account or clean matching so the bank reconciliation still ties out. |
Tip: Pick one system where invoices and bills are created, usually the accounting system. Two places that can both create invoices is how a customer gets billed twice.
If you are on QuickBooks Online, our guide to setting up QuickBooks for contractors walks through the job costing and AR setup that makes any add-on tool work better.
The reason to think about AP and AR together is cash. AP aging shows what is due. AR aging shows what should come in. Side by side, that is a working cash forecast.

This is where construction makes it harder. With pay-when-paid or pay-if-paid clauses, the sub invoice you owe is tied to the owner payment you have not received yet. Retainage sits on both sides: you are holding retainage from subs while the owner holds retainage from you. A good AP and AR setup lets you see those links by job, so you know that releasing a sub's retainage depends on collecting your own. For the receivable side of that puzzle, our construction accounts receivable guide goes deeper on retainage and pay applications.
These are the tools contractors and small to mid businesses most often look at, grouped by fit. Details were checked on each vendor's site in November 2026; confirm your tier in a demo.
BUILT-IN SUITE
QuickBooks Online already handles invoices, bills, AR aging and AP aging. Intuit's Bill Pay adds online bill payments by ACH or check, with payments syncing back to the books. Intuit says Bill Pay Elite, which adds role-based controls, custom approval workflows and an audit trail, is included with QuickBooks Online Advanced from August 1, 2026 when bought directly from Intuit, and that standard ACH bill payments are now free.
Fits: contractors already on QuickBooks Online who want AP and AR in one place without adding a vendor. Collections follow-up is basic, so many firms add a receivables tool on top.
BUILT-IN SUITE
Xero captures bills from email or uploads, supports roles for who can create and approve bills, and pays bills online through its partnership with Melio. On the AR side it sends recurring invoices, automatic reminders to late payers and online payment options.
Fits: small firms that want a clean all-in-one ledger and do not need construction-specific features like AIA billing in the core product.
CONSTRUCTION ERP
Construction accounting systems handle AP and AR with job costing built in. Sage 100 Contractor's help documentation covers retention withheld at the subcontract rate, two-party checks through secondary payees, and lien waivers that must be printed before vendor checks. Sage says Sage Intacct Construction automates lien waivers for secondary vendors and announced retainage enhancements in August 2026.
Fits: GCs and larger subs who need retainage, joint checks and lien waiver control on both sides of the ledger.
AP + AR
BILL offers accounts payable and accounts receivable on one platform. On AP, it routes bills through approval policies and pays vendors. On AR, it creates and sends invoices, schedules up to three reminders relative to the due date, and lets customers pay by ACH or card. Automatic two-way sync with QuickBooks Online and Xero sits on higher plans, per BILL's pricing page.
Fits: offices that want one add-on for both sides with real approval controls on payables.
AP + AR
Melio started as a bill pay tool and now includes a Get Paid side for receivables. Its help center says it can import invoices and customers from QuickBooks Online, send payment requests and mark invoices paid in both places once paid in full. Melio notes that edits made to invoices in Melio do not sync back to QuickBooks Online, and that sync limits depend on plan.
Fits: small businesses that mainly want an easy way to pay bills and send simple payment requests.
AP ONLY
Ramp's Bill Pay handles bill capture, approvals and vendor payments, with a free tier that includes QuickBooks Online and Xero integrations, according to Ramp's pricing page. Its paid Plus plan adds features like batch payments and two- and three-way matching.
Fits: firms that want stronger AP controls and card spend in one place. It does not handle collections.
AP ONLY
Tipalti focuses on payables at scale: supplier self-onboarding, W-9 and W-8 collection, 1099 reporting, global payments and ERP integrations including NetSuite, Sage Intacct and QuickBooks, per Tipalti's site.
Fits: larger companies with high vendor volume.
AR ONLY
Versapay is a collaborative AR platform aimed at mid-market B2B companies, with customer portals and a payment network. AR Workflow is accounts receivable automation for contractors on QuickBooks Online (more on it below). Neither one pays your bills.
Fits: businesses where getting paid, not paying, is the bottleneck.
| Tool | AP | AR | Construction features | Best fit |
|---|---|---|---|---|
| QuickBooks Online + Bill Pay | Yes | Yes, basic reminders | Projects and progress invoicing | Small contractors already on QBO |
| Xero | Yes | Yes, automatic reminders | Limited | Small firms wanting a simple ledger |
| Sage 100 Contractor / Sage Intacct Construction | Yes | Yes | Retainage, lien waivers, joint checks | GCs and larger subs |
| BILL | Yes | Yes | General purpose | One add-on for both sides |
| Melio | Yes | Yes, payment requests | General purpose | Simple bill pay plus payment requests |
| Ramp Bill Pay | Yes | No | General purpose | AP controls and spend |
| Tipalti | Yes | No | General purpose | High vendor volume |
| AR Workflow | No | Yes, collections automation | Built for contractors | Contractors on QBO with slow receivables |
Bring one overdue invoice.
We'll show you how it would be followed up, and what your customer would see.
Generic tools assume one invoice, one payment. Construction does not work that way. Check how each tool handles these.
| Need | Payables side | Receivables side |
|---|---|---|
| Lien waivers | Collect conditional and unconditional waivers from subs and suppliers before paying | Send your own waivers with pay apps so the GC or owner releases payment |
| Retainage | Track retainage payable by sub and release it at the right milestone | Track retainage receivable by job and bill for it at completion |
| Pay-when-paid | Tie sub payments to the owner payment they depend on | Know which owner payments unlock which sub payments |
| Joint checks | Issue two-party checks to a sub and its supplier | Expect joint checks from upstream on some jobs |
| Compliance docs | Hold payment until the COI and W-9 are current | Keep your own COI and paperwork current so the GC cannot hold your pay app |
| Insurance work | Pay subs on restoration jobs on your normal terms | Chase adjusters for status, homeowners for deductibles; never send an adjuster a payment link |
Most of the payables items live best in a construction accounting system or a construction-focused AP tool. The receivables items, especially consistent follow-up with homeowners and small commercial customers, are where a dedicated collections layer earns its keep. Our page on construction accounts receivable software shows how that looks in practice.
| 1 | Find the side that hurts Look at your last three months. Late fees and missed vendor discounts point to an AP problem. Invoices aging past 30 and 60 days point to an AR problem. Buy depth where the pain is. |
| 2 | Start from your ledger List the tools that connect natively to the accounting system you already run. Do not switch ledgers to get a bill pay feature. |
| 3 | Check the sync in a demo, not a brochure Create a bill and an invoice, edit both in your accounting system, and watch what happens in the tool. Ask what syncs on the plan you would actually buy. |
| 4 | Map your approval rules Who approves a sub invoice over a set amount? Who can change a vendor's bank details? Make sure the tool can enforce it. |
| 5 | Price the whole stack Add subscriptions, per-user fees and payment fees on both sides. A cheaper suite with weak collections can cost more in slow cash than a second tool would. |
| 6 | Name an owner for each tool Somebody has to watch the sync, fix errors and keep vendor and customer records clean. If nobody owns it, it drifts. |
To be straight about it: AR Workflow is not accounting software, not AP software and not a general ledger. It does not pay bills, process sub invoices or collect lien waivers. If you need payables, use your accounting system, a construction ERP or one of the AP tools above.
What AR Workflow does is the receivables follow-up that most suites treat as an afterthought. It connects to QuickBooks Online, reads your open invoices and puts each one on a follow-up schedule with automated emails, two-way texts and ringless voicemail from a dedicated number. Homeowners get a payment link so they can pay from their phone. An aging dashboard shows who owes what and who has gone quiet. QuickBooks stays the ledger. AR Workflow is the receivables layer that sits next to it.
So a common contractor setup looks like this: QuickBooks Online as the ledger, QuickBooks Bill Pay or another AP tool for paying subs and suppliers, and AR Workflow for automated payment reminders and collections. See how it works with QuickBooks collections, or compare plans on the pricing page.
It is software that automates both sides of a business's cash: paying bills (accounts payable) and collecting on invoices (accounts receivable). Some products handle both in one suite. Others specialize in one side and connect to your accounting system.
One tool is simpler if one person runs the books and neither side is a serious problem. Two tools make sense when one side, usually collections, needs more than a basic reminder feature. Either way, both should sync to the same general ledger.
Yes. QuickBooks Online tracks bills, invoices and both aging reports, and Intuit's Bill Pay adds online vendor payments. Many contractors add a separate collections tool because invoice reminders in the core product are basic.
No. Add-on tools like BILL, Ramp or AR Workflow feed your general ledger; they do not replace it. Construction ERPs like Sage 100 Contractor include the ledger along with AP and AR.
Lien waiver tracking before paying subs, retainage on both payables and receivables, joint checks, pay-when-paid timing and job-level reporting. On insurance work, the AR tool should treat adjusters differently from homeowners and only send payment links to the people actually paying.
