1. Open by design
Every serious business system today speaks the same small set of languages: web APIs that exchange JSON, token-based sign-in, and SQL for reporting. ZakERP speaks all of them. That single fact is what turns "can our systems talk?" from a year-long project into a planned piece of work with a clear finish line.
REST + JSONCreate, read, update and look up records in the other system through its published web API.
OAuth & tokensSigned, revocable access, with no shared passwords, using the sign-in method the other platform prefers.
Query languagesSuiteQL, OData and SQL, to pull exactly the rows a report or a decision needs.
Scheduled syncA built-in job engine runs each connection on its own timetable, with a history of every run.
Send queueOutgoing work waits safely until the other side answers, so a network outage costs nothing.
Files & importsCSV and Excel for systems that have no API at all, with the same audit trail.
2. Proven with Oracle NetSuite
In daily use: people, attendance and leave run in ZakERP, purchasing and finance in NetSuite. A leave application that starts in ZakERP is approved by a senior manager in NetSuite, and the answer comes back by itself.
The first levels approve in ZakERP. At the final step the request appears in NetSuite with Approve, Return and Cancel buttons, an email and a reminder. The decision flows back into ZakERP, completes the approval in the approver's name, and the employee is told.
- Approve in NetSuite: approved in ZakERP, balance updated, employee notified.
- Return with a note: back with the employee in ZakERP, note attached, ready to correct and resubmit.
- Cancel with a reason: closed in ZakERP with that reason on record.
- Administrator decides in ZakERP: the NetSuite copy is withdrawn automatically, so there is only ever one answer.
Every path passed on live systems, and the whole integration was built and tested in a single working day. Delegation works too: when an approver hands their approvals to a colleague, those requests stay in ZakERP for the delegate.
3. How a request travels
Any step in an approval chain can be set to be decided in the other system. The request goes across with everything needed to decide on one screen, the decision comes back by itself, and the work completes in ZakERP. Nothing is typed twice, and a missed moment is picked up on the next cycle.
4. Systems ZakERP can join
NetSuite is the first platform connected end to end. The same connector design works with every major business system that publishes an API, which today is almost all of them:
| Platform | How ZakERP connects | Status |
|---|---|---|
| Oracle NetSuite | REST web services, SuiteQL, token-based authentication, SuiteCloud projects | Live, proven |
| SAP S/4HANA · SAP Business One | OData and REST services (Service Layer for Business One) | Connectable |
| Microsoft Dynamics 365 | Dataverse / Business Central web APIs with OAuth 2.0 | Connectable |
| Oracle Fusion Cloud ERP | REST APIs and scheduled data extracts | Connectable |
| Odoo | JSON-RPC / XML-RPC external API | Connectable |
| Tally · QuickBooks · Xero | Their accounting APIs and data exchange formats | Connectable |
| Salesforce · HubSpot | CRM REST APIs for customers, leads and orders | Connectable |
| Banks, payment and SMS gateways | Their APIs or file formats | Connectable |
| Your in-house or legacy systems | Direct database views, SQL or scheduled files | Connectable |
"Connectable" means the platform publishes the interface ZakERP's connector is built for. Each connection is shaped around your own processes and switched on for your company.
5. What you can connect
Leave approval was the first story. The connector is general, so the same foundations carry any business object across:
TransactionsRequisitions, purchase orders, bills, payments, sales orders and journal entries, raised on one side and approved or posted on the other.
Master dataEmployees, vendors, customers, items and projects, entered once and kept in step everywhere.
Custom recordsWhatever your company has built for itself, such as bills of quantities, asset logs or site records, handled like any standard record.
ApprovalsAny ZakERP approval level decided in another system, or another system's approvals brought to the people who live in ZakERP.
ReportingFigures from the other system inside ZakERP's reports and dashboards, next to attendance, payroll and stock.
Linked recordsEvery mirrored record links to its twin, one click away.
6. Two systems, never out of step
Connecting systems is easy. Keeping them in agreement every single time is the craft. These rules are built into every ZakERP connection:
| Built-in rule | What it gives you |
|---|---|
| One owner per field | Each piece of data has exactly one home, so the two sides can never contradict each other. |
| A unique key per request | Retries and resubmissions never create duplicates. |
| The right person, verified twice | Only the named decision-maker's answer is accepted, and both systems check it. |
| Withdraw before overruling | An override on one side automatically retracts the request on the other. |
| Confirmed delivery | A decision is marked as collected only once it is safely saved. |
| Self-healing retries | If a system is unreachable, the connector waits and tries again, and the administrator is alerted once, not flooded. |
| A complete audit trail | Every hand-over and decision is recorded on both sides, with who acted and where. |
Staff always know where a request stands: every approval record in ZakERP shows a coloured status beside its title (Pending Approval, Approved, Returned or Cancelled).
7. Security you can explain to your auditor
- Signed, token-based access. Every call is cryptographically signed, no password travels, and access can be revoked in one click without touching anyone's login.
- Least privilege. The connector signs in with a dedicated integration role that can reach only the records it needs.
- Secrets stay on your server. Credentials live outside the application and outside source control, and never appear in a log or on a screen.
- No new doors. ZakERP reaches out to the other system, so an integration never adds a new way into your ERP.
- A master switch. Any connection can be paused instantly, and ZakERP carries on handling everything locally.
- Changes managed as code. Everything added to the other platform is version-controlled and validated before it is installed.
8. From idea to live link
- Map the process. Where each record starts, where it is decided, which details travel, and what happens on return, cancel and override.
- Prepare the other platform. Records, permissions and workflow, validated and installed safely in test mode.
- Switch on the hand-over in ZakERP. The queue, the scheduler, the retries and the audit trail are already in place, so this step is configuration.
- Prove every path, then go live. Approve, return, cancel and override on real systems with test data, then one switch puts it into daily use.
Because the foundations are already built and proven, each new connection is focused on your business rules, not on plumbing. That is why our first one went from question to tested integration in a day.
