Service-based businesses work very differently from product-based businesses. Instead of selling items, they sell time, skills or completed work. Because of this, creating invoices and applying GST correctly often becomes confusing in that case. Manual billing increases the chances of errors, delays and compliance issues. This is why many service providers rely on GST billing software to manage their invoicing smoothly. It helps automate calculations, maintain proper records and reduce stress related to GST compliance.
Time-based billing means charging customers according to the amount of time spent delivering a service. This model is commonly used by consultants, freelancers, legal professionals, accountants and IT service providers. The total invoice value depends on the number of hours or days worked and the agreed rate.
In time-based GST billing, tax is calculated on the final service amount derived from time spent. Billing software makes this easy by tracking billable time, calculating the payable amount automatically and generating accurate invoices without the need for manual effort.
Project-based billing is used when a service is offered as a complete project rather than hourly work. Examples include website development, branding projects, marketing campaigns or interior design services. Payments may be taken as a single amount or broken into milestones.
With project-based GST billing, GST is charged on the total project value or on individual milestone payments. Billing software helps to manage project details, keeps track of billing stages and makes sure that the invoices are raised correctly at every step.
GST is applicable to both billing models when services fall under taxable categories and the business is registered under GST. The tax rate depends on the nature of the service. Each invoice must include required details such as GSTIN, service description, taxable amount and tax breakup.
Using GST invoicing software ensures all invoices follow GST rules properly. It minimizes compliance risks and helps businesses to avoid mistakes that can lead to notices or penalties.
