What is system integration?
The jargon-free definition: what it means for your tools to be connected, the four ways it usually gets done, and how to tell whether you need it.

“Our systems don't talk to each other.” If you've said it, you know the cost: the same customer typed into three tools, invoices re-keyed from the CRM into accounting, a spreadsheet someone updates at midnight so the numbers line up. Double entry isn't just wasted hours — it's where errors and dropped balls live.
We fix that. Saltline builds system integration services for small businesses — connecting the tools you already run so information flows automatically and nothing falls through the cracks. This is the custom, complex work that off-the-shelf app-store syncs can't reach.
What we connect
CRM, accounting, and the tools that run your operation
We don't do plug-and-play app-store buttons that break on the first edge case. We build the custom integrations — API integration services and data pipelines — that fit how your business actually works.
CRM integration services
Your CRM should reflect reality without anyone updating it by hand. We wire it to your billing, scheduling, and support tools so a new customer, payment, or status change flows everywhere it needs to — automatically.
- CRM ↔ billing & invoicing sync
- Lead & contact deduplication
- Pipeline and status automation
- Two-way field mapping you control
Accounting & billing connections
Stop paying someone to copy invoices, payments, and expenses between systems. We build reliable connections between your accounting platform and the tools that feed it, with the reconciliation logic your business actually runs on.
- QuickBooks / Xero integrations
- Payment & Stripe reconciliation
- Invoice & expense pipelines
- Custom mapping and audit trails
Operations & ops-tool integrations
The spreadsheets, scheduling apps, and internal tools that run your day-to-day rarely talk to each other. We connect them with custom API integration services so data moves in one direction of truth instead of a dozen copies.
- API integrations between internal tools
- Data pipelines & scheduled syncs
- Spreadsheet & legacy-system bridges
- Migrations and data cleanup
Common integrations
Platforms we connect most often
A few of the systems we're asked to connect the most. Don't see yours? If it has an API — or even if it only has a spreadsheet — we can almost certainly integrate it.
- QuickBooks
- Salesforce
- HubSpot
- Stripe
- Xero
- Airtable
- Google Workspace
- Custom & legacy systems
How it works
Map, connect, automate, monitor
Integration isn't a one-time script you run and forget. We treat it as a system — built to keep working as your tools and team change.
01
Map
We chart every system, where data lives, and every place a human is currently copying it by hand.
02
Connect
We build the integrations and pipelines — custom where it needs to be, reliable everywhere — with a single source of truth.
03
Automate
Data flows on its own. New records, payments, and status changes propagate everywhere they belong, in real time.
04
Monitor
We watch the connections, catch failures before you do, and keep them working as your tools change.
Why it holds up
Reliable, owned, and observable
Most integration horror stories come from brittle, one-off syncs that silently break. We build differently: connections with error handling and retries so a hiccup doesn't corrupt your data, code and credentials you actually own instead of renting, and monitoring that flags a failed sync before it becomes a billing problem. When your tools change, the integration changes with them — and we're the ones who keep it running.
