What software is better for design leaflets?
Microsoft Publisher. As you are starting your business and will obviously need business stationery, leaflets, flyers, letters, business cards etc I suggest you go on a basic microsoft office training course at your local community centre or college, or better still look up your local business enterprise centre where you will get tuition in creating business plans, profit and loss statements etc which are vital if you are starting out in business as well as advice in marketing strategies.
It depends what software you already have, and whether you want to purchase new software to do this or use what you already have. I assume you have MS Word, and you can use that if you plan carefully how you lay it out – I have done it this way and put my text in columns and then printed it landscape, so it can be folded in half. But it won’t look as professional as if you used something like Microsoft Publisher.
