Paythen and Shopify, connected properly
Shopify Paythen Integration, Without the Copy-Paste
A Shopify Paythen integration has no native app, because Shopify restricts third-party payment apps. Paythen's setup guide uses a manual payment method called Paythen payment plan in Shopify plus a Zapier action that emails the customer a payment plan link, with Stripe as the processor. A premium Zap can create Shopify orders for new Paythen customers. We set up, test, from $690.
- Payment plan template and Shopify toggle set
- Manual payment method and Zapier email link
- Order status when instalments are paid
- Test log and a recorded handover

Our track record
450+ Shopify Stores Launched Since 2015. Your Paythen Connection Gets the Same Care.
A link between Paythen and your store proves its worth only if the data is right on a normal busy day. After a decade of building stores, we have learned where orders, customers and products usually break an integration, and we plan for it.

Problems solved
Shopify Paythen Integration: Six Faults We Fix First
Instalment setups fail on status and links. These are the six faults we fix.
The problem
Plan link not sent
The outcome
Customers cannot pay. We test the Zap.
The problem
Order shows unpaid forever
The outcome
Staff cannot tell progress. We update status.
The problem
Instalment missed
The outcome
Goods ship without payment. We hold fulfilment.
The problem
Duplicate orders
The outcome
Retries repeat. We check first.
The problem
Native app assumed
The outcome
No Paythen app exists for Shopify. We follow the guide.
The problem
No handover
The outcome
Setup is unwritten, so the next change starts from guesswork. We write down the triggers, fields and tests.

How the link works
Paythen and Shopify: How the Connection Is Wired
See the build as a short chain: event, check, write, log. Each link is tested on its own and again as a whole, with real orders, before we ask you to approve anything.

SkincareProcess and timeline
Six Stages From Brief to Live Paythen Sync
We follow the same six steps on every build, which is why the price can be fixed.
- 1
Brief and scope
The brief covers what you sell, how Paythen is used and which events should trigger work. We review some orders and payments to decide the starting point and the limits.
- 2
Access and connection
You approve narrow access to Shopify and Paythen, using an API key with restricted permissions. We confirm the connection with a live read before building on it.
- 3
Map and rule
Together we map charge id, order number, fee and currency, decide which system wins each clash and write down how blanks behave.
- 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
Cases tested: a paid order, a partial refund and a payment in another currency, plus refunds and edits. Every result is compared with Shopify's own figures.
- 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.

Inside every project
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.
A written definition of done
A flow is finished when it handles a paid order, a partial refund and a payment in another currency correctly and the results are logged.
Narrow access, in your name
We ask for the least access that works, through an API key with restricted permissions, and every account stays under your ownership.
Nothing sent without approval
Anything that emails, texts or posts to a customer is reviewed with you before it is switched on.
Plain scope, two revision rounds
You see the price before paying. Changes within scope go through two structured rounds, so a tweak never becomes an hourly invoice.
Build in a copy, never live
The flow is built and tested against test data. Your live orders and payments are untouched until you approve.
Counts compared, not assumed
Every load ends with a count against the source, which catches gaps and doubles quickly.

Why Store Design Expert
Why Owners Choose Our Shopify Paythen Integration Over Doing It Alone
Templates cover the happy path. We cover the rest, and we put the result in writing.
A price you can plan around
Every package and option shows its price and extra days in the calculator. Any Paythen plan fees are billed to you by Paythen, so check its current pricing page.
We live inside Shopify
Orders, refunds, edits and metafields are what we handle every day, which is a different skill from knowing Paythen's menus.
Tested on your real cases
We test the cases your store actually has, such as a paid order, a partial refund and a payment in another currency.
4.9+ from verified clients
Reviews on this page come from verified Store Design Expert clients, so you can see how projects went before paying.
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.
Experience since 2015
Over 450 Shopify stores since 2015 mean we have seen most of the odd cases that break integrations.
What we need to get started
What to Prepare Before We Start Your Paythen Integration
The list is short. Most owners have everything ready in a day.
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
No store yet? We build it in our Partner account, connect Paythen there and transfer the whole store to you, so you choose a plan only at the end.
Or share a staff login
Sharing a staff login is possible. The collaborator route is safer, though: one click removes it and no password is passed around.
Your Paythen 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 API key with restricted 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
We need one person to approve the plan and the test, plus a rule for what wins when Paythen and Shopify clash.
Your Shopify owner password and card details never reach us. Changes are made in a copy, and we note every setting we touch.
