Resources for building better software
Free calculators, procurement playbooks, and engineering field notes from the team that ships your software. Use them to estimate costs, compare ERP vs custom builds, and vet vendors before you spend a rupee, dirham, or dollar.
Built for buyers, not just builders
Everything in this library exists to help you make one of four decisions well: what to build, what it should cost, who should build it, and how to hold them accountable.
Answers before the sales call
Most software buyers start with two questions: what will this cost, and should we buy a platform or build custom? Our tools give you a defensible first answer to both in under five minutes, using published assumptions instead of a black box. You can walk into any vendor conversation, including one with us, already knowing the realistic range.
Decision frameworks you can reuse
The playbooks are written as checklists, not essays. The vendor selection checklist for software projects, for example, lists the specific questions to ask a development company before signing, including the ones about compliance, code ownership, and handover that rarely appear in an RFP template.
Field notes, not content marketing
Every blog post is written by the engineers who did the work it describes. That includes what went wrong. If a post covers a monolith migration, it names the pattern we used, the trade-offs we accepted, and where the cost actually went, so you can apply the same reasoning to your own system.
A regional lens where it matters
RNDSOL is a custom software development company in Lahore, Pakistan, delivering for clients across Pakistan, the UAE, Saudi Arabia, the UK, and the US. Where regional context changes the answer, such as GCC compliance frameworks or school management software in Pakistan, our resources say so explicitly instead of pretending one answer fits every market.
Common questions about these resources
Yes. Every calculator, playbook, and article on this site is free to use with no signup, no email gate, and no trial period. We publish them because informed buyers make better clients, and because most of this material already existed internally as our own scoping and review checklists.
It produces a range, not a quote. The calculator uses the same inputs our estimators start from: project type, feature complexity, integrations, and compliance needs. For most projects the real proposal lands inside the calculator's range, but a written estimate always follows a discovery conversation, because scope details the calculator cannot see (legacy data, third-party APIs, regulatory requirements) can move the number.
It depends on where your processes diverge from the industry standard. If your differentiation lives at the edges (approval chains, report layouts), a ready-made ERP is usually faster and cheaper. If a proprietary workflow is your competitive advantage, custom software is usually the better long-term investment. Our ERP vs custom software comparison tool walks through the five questions we ask internally before recommending either path.
Yes, link to them freely. The playbooks in particular are written to be circulated inside a buying committee: procurement teams use the software procurement guide and the vendor selection checklist as shared evaluation criteria before shortlisting development partners.
