ERP–CRM sync: what happens when the API fails
A flow with fictional data showing a successful sync, an API failure and the recovery of the affected record.
A web application has users who log in, data that changes and permissions that matter. If what you need is to explain who you are and collect enquiries, that is a website and it costs considerably less.
We ask this at the start because it changes the budget by an order of magnitude. If your case is the lighter one, we will say so.
Accounts, roles and per-person permissions. A website has none of this.
Someone creates, edits and approves records. There are states, history and a need to know who did what.
It reads or writes to the ERP, the CRM or a payment gateway while the person waits.
Calculations, validations and approval flows no template supports.
Scope
Tools for the team: daily operations, approvals and tracking, with the roles the organisation already has.
External access with authentication, bounded permissions and activity logs.
When what is missing is a screen over several systems that do not talk.
See integrations : Integration layers with a UIData from the system itself, not a report somebody exports and refreshes by hand.
Search, classification or drafting inside the application, with explicit limits and human review.
See AI agents : AI-assisted featuresWhen there are payments, bookings or inventory and the rules do not fit a standard product.
Applications fail on what a screenshot cannot show. These five are in scope from the start.
Who sees what and who can do what, enforced on the server and not merely by hiding buttons.
Deliverable: Role matrix and access tests.
What is stored, what can be deleted and how you know who changed each thing.
Deliverable: Data schema and audit log.
Authentication, sessions, input validation and handling of personal data as applicable.
Deliverable: Security review of the delivered work.
A staging environment separate from production, with repeatable and reversible deployments.
Deliverable: Configured environments and automated deployment.
Updates, monitoring and who to write to when something breaks. Agreed by contract or it does not exist.
Deliverable: Operations documentation and a support agreement if there is one.

Queries the company knowledge, answers with sources, admits when it lacks enough information and hands off to a person.
No. A website communicates and collects enquiries; a web application has users, permissions and data that changes. If your need is the first, it costs far less. We clarify this in the first conversation so as not to over-quote.
Yes, and it is the recommended path. Delivery is phased, each phase with its own working deliverable. You can stop at the end of any of them and keep it.
You can — we hand over repository, documentation and access — or you can contract support with us. Without a support contract, delivery closes at handover.
Your own systems and platforms, when no off-the-shelf tool solves the process.
Synchronisation between systems with error handling, retries, duplicate control and monitoring.
Bespoke sites and front-ends engineered rather than assembled, when a template cannot carry your content model.
Tell us who will use it and what it has to do. We will tell you which of the two you need, even when it is the cheaper one.
