How to connect your business apps so data syncs

To connect your apps, you either use a built-in integration between two apps or a workflow automation tool that moves data when something happens, such as a new order creating a sales record in your accounting software. Built-in integrations are simplest when they exist and cover what you need. Automation tools fill the gaps and can connect many apps at once.

How to connect my apps so data syncs, step by step

List the apps you use and which data you currently copy between them.
Decide which app is the source of truth for each type of data, such as customers or orders.
Check each app's built-in integrations before adding another tool.
For gaps, build the sync in a workflow automation tool, mapping each field.
Test with real records, including edits, refunds and deletions.
Set alerts for failed syncs and review the data regularly for duplicates.

Why it matters

QuickBooks 2024: businesses use 10 digital solutions on average and spend 25 hours a week reconciling data across apps. Source

What to look for

Editorial assessment

Built-in integration first A direct integration from the app makers may handle edge cases such as refunds and taxes better. Check what it syncs before building your own.
Field-level mapping You need control over which fields go where. A sync that only moves names but not tax or product codes creates cleanup work.
One-way or two-way sync Decide whether changes should flow both ways. Two-way sync without clear rules can overwrite good data.
Cost of a sync that runs constantly A sync fires on every new or changed record, not once a day. Check how the tool counts those runs and estimate them from your real order and contact volumes.
Failure alerts and logs When a sync fails, you need to know which record and why, or your books and CRM quietly drift apart.
Historical records Check whether the integration can copy existing records across once, not only new ones from today. Otherwise you start with two systems that disagree.

Common mistakes to avoid

No source of truth If two apps can both edit customer or product records, syncs will fight each other. Pick one master for each data type.
Syncing before cleaning Duplicates and inconsistent names get copied everywhere. Clean the data before the first sync.
Summary vs detail mismatch Sending every order into your accounting software may not be what your accountant wants. Decide with your accountant whether to post each sale or a daily summary.
Nobody watching the sync Syncs break when a login expires or an app changes. Name an owner who gets the alert.

What to settle before you buy

Which apps must share data, and which one owns each record type?
Should data flow one way or both ways between each pair?
Has our accountant agreed how sales and fees should reach the books?
Who owns the integrations and fixes failures?
Which past records need a one-time copy, and which only need to sync from now on?

Frequently asked questions

How do I sync Shopify with QuickBooks?

First check the integrations your store platform and accounting software offer between themselves, then compare what each one posts: individual orders or summaries, fees, refunds and taxes. Agree on the approach with your accountant before turning it on, and test with a few real orders.

How do I connect apps without coding?

Use a workflow automation tool: choose a trigger in one app, such as a new form entry, then choose the action in another, such as creating a contact. Map the fields, test with sample data and switch it on.

What should I compare when looking at Zapier alternatives or n8n vs Zapier?

Check that each tool connects to your apps with the exact triggers and fields your sync needs, then compare how runs are counted at your order and record volume, and whether you want it hosted or on your own server. Of the 3 automation tools we track, Zapier, Make and n8n list a free plan or free tier (limits are in the table above). The table above shows each tool's verified entry price and billing unit.

Can I automate workflows with AI agents?

You can add AI steps that read, sort or draft content inside an automation. Keep a human check before anything is sent to customers or written to your books, because AI output can be wrong.

How we built this page

We start from the job, not the product. The phrasings people search for this job (for example “zapier alternatives”) come from our research into how small and mid-size teams describe it. Which software categories the job takes is our editorial judgment. Every tool, entry price, billing unit and date comes from HelpCompare’s open dataset, recorded from each vendor’s own pricing page; nothing is estimated, and where a vendor publishes no price we say so. We take no affiliate commissions and publish no scores of our own. See our methodology or download the data from Open Data.
