How do I get my job software, accounting and phones to talk to each other?

The three ways field service tools connect

When a vendor says "we integrate," it can mean three very different things. Knowing which one you are getting saves you from buying the wrong plan.

• Built-in sync: The vendor built and maintains the link itself. Accounting is the usual one. You click connect, pick your accounts, and invoices flow across.
• No-code connector: Zapier or Make move data when something happens. A "Zap" is one rule: when X happens in app A, do Y in app B. I compare the two connectors in Zapier vs Make.
• API: An application programming interface is a set of rules that lets software talk to your data directly. A "webhook" is the same idea running in reverse: your tool pings another system the moment something changes. APIs do the most, but a developer has to build the link and keep it running.

Start at the top of that list and only move down when the one above cannot do the job. Most small firms never need to go past the second.

What each tool connects to

This is what each vendor says on its own pages as of November 2026. Plans change, so check the plan before you sign.

Tool	Accounting	Zapier	API
Jobber, a job and invoicing app for small home service teams	QuickBooks Online sync starts on the Connect plan ($99 a month for one user, billed yearly)	Yes, on select plans. 11 triggers and 6 actions	Public API, but private custom integrations are only for approved customers and developers
Housecall Pro	QuickBooks Online and Desktop	MAX plan, per its pricing page FAQ	MAX plan only ($299 a month billed yearly, $329 monthly)
Workiz	QuickBooks Online sync on all three plans	Ultimate plan only	Ultimate plan only
FieldPulse, a job tool for HVAC, plumbing and electrical firms	QuickBooks Online and Desktop, and Xero, per its help center	Not confirmed, so ask FieldPulse	Yes, API token from FieldPulse support
FieldEdge, a job and dispatch system for HVAC and plumbing	Ask FieldEdge which accounting packages it syncs with	Ask FieldEdge	Open API for members and partners

A few details that the table hides:

• Jobber: Its Zapier triggers include New Client, Quote Approved, New Job Completion and New Invoice. Actions include Create Client, Create Request, Create Quote and Create Job. If you want a custom build, Jobber's developer pages say custom integrations are only possible for approved customers and developers, and an app in draft state is blocked if it connects to more than 5 paying Jobber accounts. See my Jobber API guide and Jobber QuickBooks guide.
• Housecall Pro: The QuickBooks Online link runs mostly one way, from Housecall Pro to QuickBooks. It sends invoices, payments, new customers and new price book items, usually within 2 to 5 minutes. Changes made to the job after the first sync do not reach QuickBooks until you use one of its action buttons or push the invoice by hand. Housecall Pro also says it cannot give support on API requests, so budget for a developer. More in my Housecall Pro integrations and Housecall Pro API guides.
• Workiz: Its pricing page lists QuickBooks sync under all three plans, and Open API and Zapier under Ultimate only. Workiz asks you to request pricing, so get a quote for the Ultimate plan before you plan a build around it. See Workiz pricing.
• FieldPulse: Its API uses a token you request from support, sends it in an x-api-key header, and allows 50 requests per second. It also offers outbound webhooks for jobs, estimates and invoices, which FieldPulse Support sets up. FieldPulse prices by seat on a custom quote.
• FieldEdge: Its developer portal describes two kinds of users. Members are FieldEdge customers who build private integrations for internal use, supported by their own technical teams. Partners build public apps and are asked to start with an onboarding form. If you ask "does FieldEdge have an API," the answer is yes, but it is built for people with a developer. For the plain QuickBooks route, my FieldEdge vs ServiceTitan guide has the wider comparison.

How to connect two tools, step by step

Here is the order I follow. It works for any of the tools above.

1. List the handoffs. Write down every place someone retypes something. Typical ones: a paid invoice into the books, a new web lead into the job tool, a finished job into a review request.
2. Check the plan. Open your plan page and look for the words accounting sync, Zapier and API. Many firms discover the link they want sits one plan up.
3. Use the built-in sync for accounting first. It is the best supported link and your bookkeeper already knows it. Decide where invoices are created, in the job tool or in the books, and stick to one.
4. Build one Zap for one handoff. Zapier's free plan is $0 for 100 tasks a month and allows two-step Zaps. The Professional plan starts at $19.99 a month and adds multi-step Zaps and webhooks, as of November 2026. A "task" is one action a Zap performs.
5. Test with one real record. Run one client, one quote or one invoice through. Check both sides.
6. Give it an owner. Someone should see failed runs. Jobber warns that if the team member who connected Jobber and Zapier is deactivated, Zapier disconnects and needs reconnecting. A link tied to one person's login is a quiet risk when staff change.

A worked example, with made-up numbers. A plumbing shop with six technicians wants every approved quote to land in a Google Sheets (online spreadsheet) tracker and ping the office on Slack, a team chat app. That is one trigger (Quote Approved) and two actions, so it is a multi-step Zap and needs a paid Zapier plan at $19.99 a month. If the office spends 5 minutes copying each of 40 approved quotes a month, that is over 3 hours saved for about $240 a year.

Limits to know before you buy

• One-way sync is common. Many links push data out and do not bring changes back. Check which system wins when the two disagree.
• Edits after the first sync often do not travel. Housecall Pro says this plainly for invoices. Ask every vendor the same question.
• Zapier covers a fraction of each tool. Jobber's Zapier actions create clients, requests, quotes and jobs, but there is no action to edit an invoice, so some jobs need the API.
• API access can be gated. Housecall Pro locks it to MAX, along with Zapier. Workiz locks it to Ultimate. Jobber limits custom builds to approved parties. Ask before you hire a developer.
• Phones are the weak spot. Call tracking, answering and texting tools connect to different tools in different ways. Ask for the exact list of apps, not a promise of "thousands."

When a custom layer makes sense

If you are running six Zaps and a developer-built API link and still retyping data, the stack has become the problem. A small custom layer can sit in the middle: it reads from each tool's API, keeps one clean record per customer and job, and writes back. It makes sense when you pay for several tools mainly to move data between them, or when a plan upgrade costs more than the link is worth. My guide to business process automation explains how to decide what to automate, and field service management software covers the tool choice itself. If you want a pre-built list of tools that work together, see my tool stack for a field service business.

How I'd approach this

I would not start with the API. I would pick the one handoff that costs the most hours, check whether the built-in sync or a free Zap handles it, and run it for a month. If the answer is a plan upgrade, I would price the upgrade against the cost of the hours saved before I paid. And I would write down who owns each link, because the thing that breaks these setups is almost never the software. It is a password, a plan change or a departed employee.
