My workflow basically looks like this: 

1. We accept some information from a docusign form.
2. This docusign form submission updates an existing record in Airtable with the data submitted by the user. 
3. Some calculations are done on the Airtable side based on the input data. 
4. We want to populate a PDF template with these calculations then save that PDF and attach it to the same Airtable record. 

Anyone know a good way to do this in Zapier + some other tool? Ideally that doesn’t require a new paid subscription but open to it if it’s necessary.
