Customer-facing calculators
Let visitors explore a cost, time or savings estimate using business rules you provide. Make the assumptions visible alongside the result.
CUSTOM SERVICES / VIRIDLABS
Custom calculators & business tools.
Turn a spreadsheet, formula or business process into a tool people can use. ViridLabs designs custom calculators, estimators, quote builders and dashboards with clear inputs, understandable results and a workflow that fits the task.
Discuss your requirements ↗Explore our interactive concepts ↓WHAT YOU CAN BUILD
Built around the job.
Quote and configuration builders
Help customers select options and assemble a structured enquiry. An indicative estimate and a binding commercial quote should be clearly distinguished.
Dashboards and internal tools
Bring agreed information and actions into one interface, from a simple reporting view to a portal with roles and integrations.
DELIVERABLES
What we can scope.
Your proposal confirms the exact deliverables. A typical discussion covers:
- A written definition of inputs, formulas, assumptions and outputs.
- Interface design for the calculator or tool and its main user journeys.
- Implementation of the agreed rules, validation and result presentation.
- Checks against agreed example calculations and relevant edge cases.
- Deployment and handover details, with any data storage or integration requirements documented.
COST & TIMING
A quote that fits.
A calculator that runs entirely in the browser can be a compact project. Accounts, saved results, live data feeds, exports, permissions and integrations increase the scope. The source and reliability of the calculation rules matter as much as the interface.
We do not publish a fixed price or guaranteed turnaround for custom work. Send a short brief and we will discuss the scope, budget and timing before a proposal is agreed.
What to send us
Send the formula or spreadsheet, sample inputs with expected answers and a description of the users. Explain whether results are estimates or final values, which currencies or units matter and whether anything needs to be saved, exported or connected to another system.
COMMON QUESTIONS
A few useful answers.
Can you turn an existing spreadsheet into a web calculator?
Yes, subject to reviewing its formulas and dependencies. Sample inputs and verified expected outputs help define what the web version must reproduce.
Does a calculator need a database?
Not always. A calculator can run in the browser without storing user inputs. Saved projects, accounts and shared results may require a backend and database.
Can you build a pricing calculator for our services?
We can implement your pricing rules and show a clearly labelled estimate. You define the prices, assumptions and any conditions that affect the final quote.
Is the savings number on your homepage a promise?
No. It is an illustrative time-value calculation: weekly hours multiplied by hourly value and 52 weeks. It does not predict or guarantee actual savings.
