QuickBooks Integration Services

What a QuickBooks integration posts, and where it goes wrong

QuickBooks is where most small and mid sized companies keep their books, but the sales happen elsewhere: a custom ordering app, a Shopify store, a field service app, a membership platform or a Square register. A QuickBooks integration turns those business events into accounting records so your bookkeeper stops retyping them. Tepia has seen the same handful of problems undo integrations that looked fine in testing.

• Duplicate customers. Matching on name alone turns Bob’s Plumbing and Bobs Plumbing LLC into two customers with split histories. Tepia matches on a stored external ID first, then email or phone, and sends uncertain matches to a review list.
• Sales tax mismatches. If your app calculates tax one way and QuickBooks Online’s automated sales tax calculates it another, totals disagree by cents and reconciliation becomes a weekly chore.
• Payout confusion. Stripe and Square pay out batches of many charges, net of processing deductions. Posting each charge as a payment into a clearing account, then recording the payout as one deposit with the deductions, makes the bank feed match.
• Missing classes and locations. Without them, a multi location business cannot run a profit and loss by branch.

Mapping your business events to QuickBooks records

Tepia writes a posting map that ties each event in your system to a specific QuickBooks Online record. Your bookkeeper or CPA reviews it before development, because these choices decide how your reports read for years.

For high volume businesses, Tepia often posts a daily summary rather than one record per sale, which keeps QuickBooks fast and readable while the detail stays in your own database.

QuickBooks Online, Desktop, and when you outgrow both

QuickBooks Online exposes a modern REST API. Your app connects once through Intuit’s OAuth 2.0 consent screen, then posts and reads records for that company. Tepia stores tokens encrypted, refreshes them before they expire and tracks Intuit’s request limits so a busy day does not trigger throttling.

QuickBooks Desktop, including Enterprise, works differently. The integration runs through the QuickBooks Web Connector on a machine where the company file lives, polling a web service Tepia builds and exchanging qbXML messages on a schedule. It works well when that machine stays on, so Tepia adds monitoring that tells you when the Web Connector has not checked in.

Integration is not always the answer. If you run several legal entities that need consolidation, manage inventory across many warehouses, or have more finance users than QuickBooks comfortably supports, connecting more systems to it adds strain. Tepia will say so in Discovery and point you to our ERP integration services or NetSuite integration work, so the next integration is built for the system you will use in three years.

QuickBooks integrations Tepia builds most often

The projects Tepia sees repeatedly share one trait: the business has a workflow QuickBooks was never meant to run, and it needs the accounting side to follow automatically.

• Field service and home service apps that turn completed jobs, parts used and signatures into billed transactions with the technician and branch attached. See our field service management software page.
• Custom ordering and ecommerce apps that post daily sales, tax and refunds by channel.
• Membership and subscription platforms that bill recurring plans through Stripe and need deferred revenue handled correctly.
• Time tracking tools that push approved hours for job reporting and payroll.
• Zapier replacements for companies whose QuickBooks zaps have multiplied and started failing quietly, a pattern covered in Zapier vs custom integration.

Tepia designs each one with a sync log your office staff can read, so a rejected record shows the reason QuickBooks gave and can be fixed and resent without a developer.

How Tepia approaches QuickBooks integration

Tepia’s six phase process scales down well for QuickBooks projects, with a US based project manager running each one.

1. Discovery: a review of your chart of accounts, items, classes, locations and tax setup, an interview with your bookkeeper or CPA, and a look at the source system’s API. Deliverables are an Investigation Summary, an Interview Summary and User Stories such as a bookkeeper reconciling a weekly payout in one step.
2. Design: the posting map, customer matching rules, error handling, and the layout of the sync log screen.
3. Development and Testing: builds against an Intuit sandbox company, an Alpha replaying a past month of transactions, and a Beta where your bookkeeper compares QuickBooks reports with the source system.
4. Training: a short session for office staff on reviewing matches, fixing rejections and reconnecting the company if access is revoked.
5. Launch: a start date aligned with a closed period, optional backfill of open balances, and close monitoring through the first month end.
6. Support: fixes when Intuit changes its API, bug tracking and new mappings as you add products or locations.

A focused QuickBooks integration usually sits at the short end of Tepia’s typical ranges: Discovery of a few weeks to 3 months and development and QA of 2 to 6 months. See our process or contact Tepia to talk through your setup.
