Self-serve portals that take the phone calls out of doing business with you. Designed and shipped for B2B SaaS companies, not generic templates with b2b saas swapped in.
Most B2B SaaS companies are operating on sites or software stacks built three to five years ago for a different version of the buyer. Engineering velocity can't keep up with the roadmap, so the integrations and features customers demand keep slipping quarter to quarter. The infrastructure decisions that compound are the ones made with the operator in the room, not the ones made in a vacuum.
Inparlor's Customer, Vendor & Dealer Portals engagement for B2B SaaS companies reflects that. We build the portals your customers, vendors, and dealers log into to do business with you without picking up the phone. The deliverables below are scoped against the unit economics, your AOV and retention, trial-to-paid conversion of 8-25%.
Where most agencies treat B2B SaaS companies as another vertical to learn on, we treat the vertical as the starting point. Accumulated technical debt makes every new feature slower and riskier to ship than the last. We will tell you on the first call which of those constraints is binding and which is solvable inside the engagement.

Business Portals proposal turnaround
Before any screen gets built, we define who sees what, customers, vendors, internal staff, and what each role can do. Permissions are the foundation, not a setting bolted on after the portal ships and someone sees data they should not.
Customers place orders, check status, and pull invoices without emailing anyone. The flows that flood the phones and inboxes today become self-serve, so the team handles exceptions instead of routine lookups.
The portal reads and writes against the systems of record, so orders, inventory, and invoices stay consistent with the ERP and accounting tools instead of drifting into a parallel copy nobody trusts.
We launch to one user group, internal staff or a pilot set of customers, prove the flows, then widen. Each audience comes online when its workflows are solid, so a rough first version never hits everyone at once.
