When off-the-shelf SaaS is the right call
If a mature product already does the job and it is not where you differentiate, buy it. You move faster, pay less upfront and get maintenance for free. Most marketing, comms, accounting and scheduling needs are solved this way, and a custom build there is wasted budget.
When a custom build pays for itself
Build when five tools still need manual glue, when approvals, pricing or reporting fit no product on the market, or when you are renting the workflow logic that defines how your agency runs. An owned system removes the recurring copy-paste and does not disappear when a subscription lapses or a connector breaks.
How Standen scopes a build vs buy decision
We map the workflow, score repetition, integration depth and ownership risk, then scope the smallest useful build. Launch ships in 14 days from £5,000, Scale in 21 from £9,500 and Enterprise in 30 from £18,000, with 100% code ownership on handover.
Frequently asked questions
Is custom software more expensive than SaaS?
Upfront, usually yes. Over two to three years a fixed-scope build from £5,000 often costs less than stacked subscriptions plus the manual work they leave behind, and you own the asset instead of renting it.
Can we start with SaaS and build later?
Yes. Many teams buy off-the-shelf to start, then build the one workflow that becomes a bottleneck. We scope that first build around the highest-friction handoff.
What do we own at the end?
Everything: source code, deployment access and documentation. No licence lock-in and no platform dependency.
