## About

Selleris runs CRM implementation differently — as a continuous ROI loop. Every piece of work is broken into a sprint-sized task, priced at a fixed cost, and approved by the client on its expected return, in money, before anything is built.

Most CRM projects are scoped around features and go-live dates, billed by the hour, and run on long tasks that drift in scope and balloon in cost. Six months later the software is configured, training is done, and nothing in the business has changed. We rebuilt the model to close that gap at the smallest unit of work — the individual task. Estimation variance is ours to absorb, not yours. New requirements become new tasks with their own ROI, never mid-project budget renegotiations.

Clients approve each task, and watch it get delivered, inside Selleris Connect — our client portal, where the expected ROI and the technical detail sit side by side. Approval cycles drop from days to hours, because the question is "is this investment worth it?", not "what does this ticket mean?"

We're certified across HubSpot, Microsoft Dynamics 365, and Bitrix24 — three fundamentally different CRM categories. So the platform recommendation is an output of the ROI model, not a starting assumption built to sell whatever we already have. Beyond configuration, we deliver custom development on Microsoft Azure: portals, AI agents, and integrations with ERP, finance, and operational systems — all scoped through the same loop.

Since 2017, across the US and Europe: 407 projects delivered, over $50M in measurable client value at a 6x average return. The methodology is the reason those numbers exist.
