Custom CRM Development

EVERYRELATIONSHIP,ONERECORD

We build CRM systems around your actual sales process and customer data model, for companies whose pipeline, pricing or account structure no longer fits a packaged CRM without heavy customization.

01Our Approach

We model your customers, deals and handoffs as they really are, so the CRM records the work instead of adding more of it.

02Overview

A CRM shaped by how your team sells

  • 01Custom sales pipelines
  • 02Field sales apps
  • 03Forecasting dashboards

A custom CRM stores your accounts, contacts, deals and activities in a model that matches your business, with pipeline stages, required fields, approvals and automation written for your process. We build the web application, an optional mobile app for field teams, integrations with email, calendar, telephony and finance tools, and the reports sales leaders use to forecast. Your data stays in a database you control.

For a standard sales motion, Salesforce, HubSpot or Pipedrive is usually the sensible choice. Custom becomes worthwhile when your deals have unusual structures, when the CRM must drive operations after the sale, when per-seat fees are high for a large team, or when customizations have made the packaged tool fragile. We design with the reps who will use it, then pilot before full rollout. CashFish, a live finance and CRM product our team works on, is one example: its case study shows a sales pipeline running beside invoices and cash insights.

03What We Do

Capabilities, End to End

01
Customer data model

Accounts, contacts, deals, products and your own objects, such as sites, policies or properties, are modeled with the relationships and history your business actually needs to track.

02
Pipeline and deal flow

Stages, exit criteria, required fields, approval steps and multiple pipelines per product line or region reflect how deals progress in practice, with a board and list view for each.

03
Sales automation

Lead capture, scoring, assignment rules, follow-up tasks, reminders and email sequences run automatically, so reps spend their time on conversations instead of data entry and chasing.

04
Communication sync

Email and calendar sync through the Gmail API and Microsoft Graph, call logging with Twilio and document signing place every customer interaction on the account timeline.

05
Field sales mobile app

A React Native app gives field reps their accounts, route, visit notes and order entry on a phone, working offline and syncing when a connection returns.

06
Forecasting and reporting

Pipeline value, conversion by stage, activity, win and loss reasons and forecasts by rep, team or territory are reported from live data with drill-down to the deal.

06How It Runs

From Kickoff to Launch

01
Sales process mapping
02
Model and prototype
03
Build and integrate
04
Pilot and rollout
01
Sales process mapping

We interview reps, managers and operations, follow real deals from lead to invoice, and document stages, handoffs, data needs and the reports that leadership relies on today.

02
Model and prototype

The data model, permissions and key screens are designed and prototyped, then tried by a few reps on realistic scenarios to confirm that logging a deal takes less effort than before.

03
Build and integrate

We build the pipeline, automation and reports, connect email, calendar, telephony and finance systems, and run trial imports of your existing CRM data until the records reconcile with the source.

04
Pilot and rollout

One team uses the CRM for live deals first, we adjust based on what they report, then migrate the final data, train everyone and retire the old system on a date we set together.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Your pipeline does not fit a packaged CRM

Reps keep side spreadsheets because the CRM cannot represent your deals, admins maintain a pile of custom fields and scripts, and license costs rise with every hire. You want one system that mirrors the real process and connects sales to delivery, billing and support.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

When the gap between your process and the product is permanent. Signs include deal structures the standard objects cannot hold, heavy custom code that breaks on upgrades, a need to run operations after the sale in the same system, strict rules about where data lives, or seat fees that outweigh a build for a large team. If your sales motion is conventional, stay with the packaged tool.

Yes. We export accounts, contacts, deals, activities, notes and attachments through the vendor's API or export files, clean duplicates and inconsistent values, and map each field to the new model with your sales operations lead. Imports are scripted and rehearsed several times, with counts and totals compared after each run. History such as stage changes and email threads is preserved where the source system exposes it.

Sales processes change, so the CRM is built to change with them. We make stages, fields, required information, assignment rules and email templates editable by your administrators through settings screens, without a developer. Larger changes, such as a new product line with its own pipeline or a new integration, are development work, and remain manageable because you hold the code and the data model is documented.

Yes, when reps work away from a desk. We build it in React Native so one codebase serves iOS and Android. It focuses on what matters in the field, the day's visits, account details, quick notes, photos, order entry and check-ins with location. Data is stored on the device and synchronized when signal returns, with conflict rules defined in advance so two people editing one account do not overwrite each other.

Adoption is decided by whether the CRM saves a rep time. We involve reps in the design, remove every field nobody uses, capture emails, calls and meetings automatically, and make the common actions quick on a phone. A pilot team works in it first and their objections are fixed before rollout. Managers then run pipeline reviews from the CRM itself, which gives everyone a reason to keep it current.
