B2B Platform Development
in Washington, D.C.

Connecting a portal to an ERP sounds like a single decision. In practice it is dozens of small ones. Every field a partner can see or change has to be classified: does it update instantly, after a short delay, or once a day. Treating the whole integration as one pipe, moving everything the same way, causes more problems than it solves.

Stock counts belong at the fast end. A partner who reserves the last few units of a part expects the number on screen to reflect that within moments, not after an overnight batch runs. Building this path usually means a lightweight event, sent the instant a warehouse system posts a movement. The alternative is a portal polling the ERP on a timer. That leaves a window where the count is simply wrong, and a wrong count is worse than a slow one.

Pricing rarely needs that speed. A price list tied to a contract changes on a schedule, not by the minute. Pulling it once a day is enough. Even once a shift will do. It also puts far less load on the ERP than constant lookups for a number that almost never moves during a single browsing session.

Customer master data sits somewhere in between the two. A new contact added on the ERP side should appear in the portal soon. A short delay of a few minutes rarely matters here, since nobody is placing an order in that exact window. Treating every minor edit like a stock movement, with instant events for each one, adds engineering cost for a benefit nobody actually notices.

The harder question is what should never flow back automatically from the portal into the ERP. A submitted order can safely create a draft sales order on the ERP side, ready for someone to review. Posting a payment, adjusting a ledger entry, or closing an invoice should not happen from a partner action alone. Those steps stay with a person inside the finance process. The portal only feeds that person the information needed to decide, nothing more.

Getting this split right takes a working session with whoever owns the ERP, not a generic sync setting borrowed from another project. The goal is not maximum speed everywhere. It is speed where it changes a decision a partner makes right now, and restraint everywhere else. That balance keeps the integration fast. It also keeps the integration from becoming fragile under its own weight over time.
