PDFShift’s product materials do not say that it calculates GST, decides which tax rules apply, or establishes that an invoice meets Indian statutory requirements. Your application must own invoice data and tax logic; any applicable e-invoice reporting and authentication are separate responsibilities.
What PDFShift does—and what it does not do
PDFShift describes its service as a platform for converting HTML documents to PDF through an API. Its FAQ names customer invoice generation as a use case. The service can render an invoice template that your application has populated; PDFShift’s product materials do not establish that it calculates tax, selects the right tax treatment, validates invoice particulars, or registers an e-invoice.

For an invoice pipeline, keep three jobs distinct:
- Invoice and tax logic: your product determines the transaction facts, applicable tax treatment and values.
- Document rendering: your application supplies invoice content and PDFShift converts HTML or a URL into a PDF.
- GST e-invoice compliance, where applicable: your business handles reporting and authentication through the designated process.
That boundary is the main consideration for an Indian SaaS team evaluating PDFShift: it is a renderer, not a substitute for billing or tax software.
How the PDFShift integration works
The documented v3 endpoint is POST https://api.pdfshift.io/v3/convert/pdf. The product-page example uses an X-API-Key header and a source value. The official Python guide demonstrates submitting raw HTML. PDFShift recommends raw HTML when possible because it avoids a fetch of the source page, supports pages that are not publicly accessible, and can reduce conversion time.

Build the invoice HTML in your application
Generate the HTML from trusted, validated invoice data on your server. Escape customer-supplied values before inserting them into HTML, and avoid exposing API keys or sensitive billing data in browser code. A raw-HTML request is suitable when the invoice is generated from application data and does not need to be hosted at a public URL.
Send the conversion request
Use the endpoint and authentication header documented by PDFShift. Keep the key in server-side secret storage, check the HTTP status and content type, and treat the returned bytes as the PDF only after handling errors. PDFShift’s documentation establishes the endpoint, header and source field, but does not provide a complete current request schema or a verified language-specific runnable example; confirm the exact payload fields and response behavior in PDFShift’s current API documentation before deployment.
Test the rendered output
Use representative invoices to check fonts, page breaks, long item descriptions, multi-page totals, non-Latin characters, and the placement of tax and recipient fields. Compare the resulting PDF against the data your application intended to render; successful conversion alone does not prove the invoice is correct.

Indian GST invoices: rendering is not compliance
CBIC tax-invoice rules specify substantive invoice particulars. Depending on the case, these include supplier name, address and GSTIN; a consecutive invoice number unique for a financial year; issue date; recipient details where applicable; HSN code for goods or accounting code for services; description; total and taxable value; tax rate and amount; and conditional particulars such as place of supply, delivery address, reverse-charge status and signature. This is a summary, not a determination of which provisions apply to a particular transaction or taxpayer.
Your application needs to decide which fields and tax treatment apply, populate them correctly, and preserve the data needed to reproduce the document. PDFShift can display what it is given; a PDF render does not validate that the supplied particulars are complete or legally correct. Have qualified GST counsel or an accountant review the implementation against current rules and the facts of your business.
E-invoice registration is a separate step
GSTN-hosted IRIS IRP guidance describes e-invoicing as electronic authentication of covered B2B invoices and related documents. The latest mandate phase shown in that guidance is for taxpayers with aggregate annual turnover of ₹5 crore or above, effective from 1 August 2023. The guidance also says businesses continue generating invoice documents through their own accounting, billing or ERP systems and may retain their own invoice format.

Pricing, quotas and operating limits
The figures below are PDFShift’s FAQ snapshot accessed on October 3, 2026. They are vendor-published terms, not a quote or a service-level commitment; confirm current pricing and limits before budgeting.
| Item | Vendor-published detail | Planning implication |
|---|---|---|
| Free quota | 50 credits per month | Useful for limited evaluation, but estimate production usage before relying on it. |
| Credit accounting | One credit covers up to 5 MB of generated output; a 14 MB output counts as three credits. | Measure actual output sizes, especially for image-heavy or multi-page invoices. |
| Boost plan | $24 per month for 2,500 credits | Vendor FAQ pricing accessed October 3, 2026; verify the current plan and billing terms. |
| Boost overage | $0.03 per overage conversion, as described by the FAQ | Overage is disabled by default according to the FAQ; decide deliberately whether to enable it. |
| Annual billing | Annual plans cost ten months’ price, according to the FAQ | Confirm eligibility and current terms at purchase. |
| Usage notifications | At 50%, 80% and 100% usage, according to the FAQ | Notifications are not a replacement for application-side usage monitoring. |
| Default timeout | 30 seconds on Free; 100 seconds on paid plans | Vendor-stated defaults; account or request configuration may affect behavior. |
| Default parallelism | 50 simultaneous conversions | A default limit, not evidence that every workload will sustain a given throughput. |
Estimate cost from expected monthly conversions and generated-output sizes rather than invoice count alone. Include retries and unusually large documents in load planning, and check the current account settings for timeout, overage and concurrency behavior.

Authentication, data handling and privacy
PDFShift’s help says the API key belongs in the X-API-Key header. Its help article says the service switched from Basic Auth on May 6, 2025. It also warns that missing authentication can put a request into unauthenticated mode and produce a watermark. Test for the expected watermark-free result during integration, and ensure the deployed client sends the key in the documented header.
Invoice PDFs can contain personal and commercial information. PDFShift’s terms place responsibility for applicable privacy and data-protection compliance, notices and consents on the customer, and say customer data may be processed, transferred or stored in the US and other countries outside the EU. Its FAQ says ordinary conversions are not stored, while also explaining that supplying filename stores output on Amazon S3 and that customers can route output to their own S3. These are vendor statements and contract terms, not an independent security audit.
Before transmitting production invoices, review the current DPA, privacy policy, contract and actual request configuration. In particular, understand whether your selected options persist outputs, where data may be processed, and what notices or safeguards your business needs. Avoid sending real customer records in development tests unless your data-handling arrangements permit it.

How to evaluate PDFShift for your invoice workload
No independent conversion test or head-to-head comparison is established here. Run your own representative workload before choosing a renderer:
- Prepare realistic documents: include single- and multi-page invoices, long descriptions, varied tax rows, relevant scripts or fonts, and the languages and scripts your customers use.
- Check fidelity: review CSS layout, page breaks, repeated headers or footers, font rendering, dynamic content and large-output behavior.
- Compare source modes: assess raw HTML against URL rendering for your architecture, including whether documents need to be private and whether source fetching adds a dependency.
- Exercise failure paths: test invalid authentication, malformed input, slow or unavailable source pages if using URLs, timeout handling and retries. Confirm how your integration distinguishes a failed conversion from a valid PDF.
- Model operations and cost: use actual output sizes and monthly volume, then check timeout, concurrency, notifications, overage settings and any asynchronous or bulk needs against current product documentation.
- Review data governance: verify key management, storage behavior, retention and processing terms for the exact configuration you plan to deploy.
PDFShift may fit if your need is hosted HTML-to-PDF conversion and you are prepared to own the invoice content, compliance logic and integration controls. PDFShift’s product materials alone do not establish how it performs on your templates, whether its current options cover a specific workflow, or whether it meets your legal or security requirements.
Screenshot alternative for visual captures
If part of your workflow also needs website screenshots—for example, visual captures of a public invoice preview—ScreenshotNeo is a separate screenshot API and MCP server, not a replacement for PDFShift’s HTML-to-PDF invoice rendering. It is the alternative to try first for that screenshot use case because it removes cookie banners, popups and chat widgets before capture, bills only clean shots, and has a free plan with 1,000 screenshots per month and no card.

Frequently Asked Questions
Does PDFShift calculate GST for invoices?
PDFShift’s product materials describe document conversion and do not say that it calculates GST or determines an invoice’s tax treatment.
Does a PDFShift-generated PDF count as a GST e-invoice?
No. PDF rendering alone does not perform the reporting and authentication required for covered e-invoices.
Can I render an invoice that is not publicly accessible?
PDFShift recommends raw HTML, which avoids fetching a source page and can be used for pages that are not publicly accessible. Verify current request requirements in its documentation.
