Yes, the usage of handwritten invoices by window replacement and pesticide companies has indeed been noticed in several areas. The story behind this seemingly old-school practice often boils down to a couple of reasons:
1. **Personal touch**: With everything being digitized nowadays, adding a personal touch to business transactions comes as a breath of fresh air. Depending on the handwriting, it could create an impression of care and personal attention to the chores at hand.
2. **Trust building**: By providing a handwritten invoice, these companies might be trying to build trust with the clientele. It may come across as a locally owned business, where 'keeping it simple' might reassure customers about less chances of being cheated.
3. **Cost Saving**: Digital systems can be pretty expensive. If the business is small, a handwritten invoice, often on carbon paper for record keeping, can be a more practical, cost-effective approach. There's also no need for training staff members to use complex digital systems for invoice generation, which works out to further cost-savings.
4. **Illustration**: Especially for window replacement and pesticide companies, where specifics of work done can be explained better by simple illustrations or sketches, a handwritten format comes in handy.
However, while some customers might welcome this vintage charm, others might find it unprofessional and difficult to understand, especially if the handwriting is not particularly clear. Also, it could complicate the accounting process as keeping a systematic record of such invoices can prove to be a daunting task. Therefore, the effectiveness of this method really depends upon the type of clientele and the scale of the business.
