Build vs Buy a DMS — In-House vs SalesPort (2026)
Should you build a distribution management system in-house or buy one? Building looks cheap until you cost the architecture, mobile apps, scheme engine, integrations, and the 18–24 months of opportunity cost — then maintain it forever. This page compares building in-house against deploying SalesPort, factually, so founders, CIOs, and CFOs can make the call with real numbers.
The build estimates here are based on what we have observed across 45 enterprise deployments — typical engineering team sizes, salaries, and timelines to reach parity with a production DMS. Your numbers will vary with scope and team; treat these as a planning model, not a quote.
Feature Comparison
A factual side-by-side based on each platform's public information.
| Feature | SalesPort | Building In-House |
|---|---|---|
| Time to production | 4–8 weeks | 18–24 months to parity |
| Upfront cost | From ₹1.5 Lakh deployment | ~₹4 Crore (team + 24 months) |
| DMS + SFA core | Yes — proven in production | Build from scratch |
| Scheme & claims engine | Yes — battle-tested | Complex to build correctly |
| Offline-first mobile apps | Yes — 2.3 Lakh users | Hard to build & maintain |
| Milk procurement module | Yes — 83,785 farmers | Specialist domain build |
| Tally / SAP integration | Yes — in production | Build & maintain per ERP |
| GST e-invoicing | Yes — NIC-aligned | Build & keep compliant |
| Ongoing maintenance | Included in AMC | Your team, forever |
| Scaling cost | Flat AMC | Grows with the codebase & team |
| Proven at scale | ₹8,572 Cr GMV, 45 companies | Unproven until you build it |

Where SalesPort Stands Out
Specific strengths that matter when evaluating Building In-House alternatives.
Live in weeks, not years
SalesPort is in production in 4–8 weeks. Building parity in-house — architecture, scheme engine, offline mobile apps, integrations, analytics — typically takes 18–24 months before it's reliable, during which your distribution stays on spreadsheets and competitors move.
A fraction of the cost
Across 45 enterprises, building parity with SalesPort costs on the order of ₹4 Crore in team and opportunity cost over two years. SalesPort starts at ₹1.5 Lakh deployment plus flat AMC — and someone else carries the maintenance burden forever.
Battle-tested correctness
The hard parts — scheme/claim logic, offline sync conflict handling, GST e-invoicing compliance, ERP integration — are already solved and proven across ₹8,572 Crore of GMV. An in-house build rediscovers every edge case the hard way.
Maintenance and compliance handled
Tax rules, OS updates, security patches, and new integrations are included in the AMC. An in-house DMS is a permanent engineering commitment that competes with your actual product roadmap.
Where Building In-House Stands Out
Honest strengths of Building In-House — worth knowing before you decide.
Total control and IP ownership
Building in-house gives you complete control of the roadmap, full ownership of the IP, and the ability to model a genuinely unique process exactly as you want it. For a company whose distribution model is a core, unusual competitive advantage — and who has the engineering depth to sustain it — building can be the right strategic call.
No vendor dependency
An in-house system means no third-party vendor in your critical path — no AMC, no external roadmap, no migration risk if a vendor changes direction. Organisations with strong, permanent engineering teams may value that independence.
Perfect process fit
A bespoke build can fit an idiosyncratic distribution process with zero compromise, where any packaged product requires some adaptation.
Pricing Comparison
Two different pricing philosophies — pick what fits your team size and growth.
Who Should Choose What
Both platforms have strengths. Here is a clear-eyed view of best-fit scenarios.
- Companies that need distribution working in weeks, not years
- Founders and CFOs who have costed a real in-house build honestly
- Teams who want engineers focused on their core product, not internal tooling
- Businesses wanting maintenance, compliance, and scaling handled
- Companies whose distribution model is a genuine, unusual IP advantage
- Organisations with strong permanent engineering teams and a mandate to own it
- Businesses requiring zero third-party dependency in the critical path
