Fit
Is this right for you?
Usually the right call when one of these sounds familiar.
The same data typed twice
Staff copy details from one system into another.
Two systems that disagree
Orders, stock or customers differ depending where you look.
A tool with no way in
A system you rely on offers no connection to the others.
Connections that break quietly
Nobody knows a sync failed until a customer complains.
Not the right service? A new application, not a connection: Web apps. A shop that needs payments built in: E-commerce.
Scope
Scope and what you get
Each piece of work has a matching thing you receive.
- What we do
System and data mapping
We list the systems, what each holds and which data has to move between them.
What you receiveA clear map
A written diagram of systems, data and the direction it flows.
- What we do
API design
REST or GraphQL endpoints designed around what the consumers need, with versioning in mind.
What you receiveA documented API
Endpoint descriptions and examples your developers can follow.
- What we do
Connections to other systems
Integrations with payment, CRM and legacy systems, including those without a modern interface.
What you receiveWorking integrations
Connections you can run and monitor, with credentials handled safely.
- What we do
Error handling and logging
Retries, alerts and logs so a failed message is visible and can be replayed.
What you receiveFailures you can see
Logs and alerts your team can read, with notes on how to recover.
Use cases
Relevant use cases
Practical situations where this service is put to work. Open a card to see how it applies.
Connecting a shop to stock and accounts
Orders, stock levels and invoices kept in step across the systems that hold them.
- Orders passed to accounting automatically
- Stock updates reaching the shop
- Mismatches logged for review
An API for your own app or partners
A documented interface so your app, or another company's, can use your data safely.
- Endpoints and examples written down
- Access keys and limits per consumer
- Versioned, so changes do not break users
Reaching a legacy system
A bridge to an older system that offers no modern interface.
- A layer between old and new systems
- Data checked as it crosses
- The old system left untouched where possible
Sample use cases, drafted as placeholders. The Plethora team confirms the final list.
Process
How it works
Each stage is agreed with you as we go. Each shows what we do and what we need from you.
Map
We doWe list the systems, the data and the events that should trigger a transfer.
You doYou give us access to the systems and tell us who knows each of them.
Design
We doWe propose the interface, message formats and error rules, with options written out.
You doYou choose between the options and approve the design.
Build
We doWe build and test each connection, first against test accounts and then live.
You doYou review the results and confirm the data looks right.
Hand over
We doWe document the connections, set up alerts and walk your team through recovery.
You doYou take over the credentials and monitoring, or ask us to keep an eye on them.
Quality
Quality and handover
How the work is checked, accepted and passed to you.
Tested before live
Each connection is tried against test accounts before it touches real data.
Failures are visible
Errors are logged and alerts reach the people who can act on them.
Secrets kept apart
Keys and credentials are held in a secrets store, not in code.
Written documentation
Endpoints, data formats and recovery steps are written down for your team.
Tools
Tools and technology
Tools we use in delivery. We choose them to suit your team, and the list does not imply any partnership. Logos belong to their owners.
- Node.js
- TypeScript
- PostgreSQL
- Docker
- GitHub Actions
- Sentry
Engagement
Engagement and cost factors
Ways to work with us
A scoped project
A defined set of connections, built and documented.
A team alongside yours
Our engineers work with yours on the systems involved.
Ongoing support
We keep the integrations running as the systems around them change.
What shapes scope, timing and cost
- How many systems are connected
- Whether each system offers a modern interface
- How much data moves and how often
- Security and compliance requirements
- Rules for handling errors and retries
- How much support you want after handover
Scope and cost are confirmed with you in writing before work starts.
FAQ
Frequently asked questions
We recommend one from who will use the API and what they need, and explain the reason.
Often. Options include file exchange, database access or a small bridge. We assess what the system allows.
Failures are logged, retried where it is safe, and raised as alerts. We agree the recovery steps with you.
You do. It is delivered to your repositories with documentation.
