BooksHow We Build Your Invoice Ninja Integration, Step by Step
A fixed order of work keeps the project predictable. You know what happens next at every point.
- 1
Brief and scope
We ask what you sell, how Invoice Ninja is used and which events matter. A short review of your orders and invoices shows where the flow should start and what it must never do.
- 2
Access and connection
We ask for the smallest access that works, via an OAuth sign-in with accounting permissions. A live read confirms it before we build on top of it.
- 3
Map and rule
Invoice number, tax code, account and amount are matched across both tools, and we record who wins each conflict and how blanks are treated.
- 4
Build in a copy
Nothing is built on live records. The flow runs on test data first, and you see the plan, plus a recording if useful.
- 5
Test on real cases
The tests cover a paid order, an accepted quote and a payment, along with refunds and edits, and we check each result against Shopify.
- 6
Go live and hand over
Once you approve, we switch the flow on, watch the first runs and hand over notes, a diagram and a short recorded tour.
Which Route Fits: DIY, Platform, Gig or Specialist Build?
The cheapest route is not always the best value. These rows show where the differences appear.
| What matters | Invoice Ninja app or DIY | Automation platform | Freelance gig | Store Design Expert |
|---|---|---|---|---|
| Every field mapped by design | Basic defaults | Yes, if you build it | Varies | Yes |
| Duplicates blocked by a unique key | Rarely handled | If you add it | Rarely | Yes |
| Failures alert a named person | No | If you add it | Rarely | Yes |
| Edge cases checked: refunds, edits | Not often | If you test it | Varies | Yes |
| Price known before work starts | Subscription only | Plan fees and your time | Yes | Yes |
| A written and recorded handover | No | No | Rarely | Yes |
| You own every account | Yes | Yes | Varies | Yes |
| Aftercare | Vendor help desk | Platform help desk | Varies | Included for a period |
How We Protect Your Orders and Customer Data
Integrations move customer data between systems, so mistakes are costly. These practices come with every package and explain why a fixed fee can still be a careful one.
Narrow access, in your name
We ask for the least access that works, through an OAuth sign-in with accounting permissions, and every account stays under your ownership.
A written definition of done
Done means the flow copes with a paid order, an accepted quote and a payment, and the results are written in the log.
Counts compared, not assumed
We check totals against the source after each load, so mismatches surface straight away.
Nothing sent without approval
No message to a customer goes live until you have read and approved it.
Build in a copy, never live
The flow is built and tested against test data. Your live orders and invoices are untouched until you approve.
Failures raise a flag
When a run fails, a named person is told which order and why. Silence is never taken as success.
Choose Your Invoice Ninja and Shopify Package
Start with the scope that matches your store, then adjust for volume, direction and history. You see the fixed price before you pay.
Request a custom quote
Custom objects, unusual authentication, several Shopify stores feeding one Invoice Ninja account, stores above 10,000 orders a month, and builds that need your own servers are quoted separately at a fixed price.

Experience since 2015
More than 450 Shopify stores have passed through our hands, so we have met most of the quirks that interfere with integrations.
A direct line to the builder
Ask the person who built it. Questions about triggers or fields get a direct reply.
Notes a colleague can follow
Our handover records what moves where and which settings were chosen, so a future developer will not have to guess.
Getting Started: What We Ask For
We need a way into your store, a Invoice Ninja account and a short brief. Pick the access route that suits you.
Approve a collaborator request
If the store is live, send us its address and approve our request. Ownership stays with you, our role is limited, and removal takes one click.
Starting from nothing? We build first
We can start in our own Partner account, set up the store and the Invoice Ninja link, then transfer ownership to you. A Shopify plan is chosen at the end.
Or share a staff login
If it is simpler, a staff login will do. We prefer the collaborator route because it is revocable in one click and no password changes hands.
Your Invoice Ninja access
You can create the account and invite us, or we can create it with your email. In both cases you hold the owner role, and we connect using an OAuth sign-in with accounting permissions.
Sample records
Share a few typical records from both tools, or point us to them. Real examples reveal how your data is really structured.
A decision-maker
Tell us who approves the plan and the test, and which rule should win when Invoice Ninja and Shopify disagree.
Your Shopify owner password and card details never reach us. Changes are made in a copy, and we note every setting we touch.
